Norethisterone: Effective Period Delay Treatment

What is Norethisterone?

Norethisterone is a prescription medication designed to delay your period, offering convenience for special occasions or personal preferences. It contains 5mg of synthetic progesterone, which mimics the naturally occurring hormone in the body, enabling effective period postponement for up to two weeks.

This treatment works best when taken three days before your period. If you choose to stop the course earlier, your period will typically resume within 2–3 days.

How Does Norethisterone Work?

Norethisterone prolongs the menstrual cycle by maintaining high levels of progesterone, which prevents the uterus lining from shedding.

The Process:

  1. Progesterone levels naturally drop before a period, causing the uterine lining to break down.
  2. Norethisterone prevents this drop, delaying menstruation.
  3. Once you stop taking Norethisterone, progesterone levels decrease, and your period begins within a few days.

Benefits of Using Norethisterone

The primary benefit of Norethisterone is a period delay. Additionally, it may be used to treat:

  • Heavy menstrual bleeding.
  • Painful periods.
  • Premenstrual symptoms (PMS).

Dosage Instructions
